Formed from the slow crystallization of magma beneath the Earth's crust, typically during continental collision events over millions of years.
Uses & applications
Used widely in commercial dimension stone, countertops, monuments, and as a raw source for industrial minerals.
Geological facts
Muscovite mica gives this granite its distinct reflective sparkle; it is one of the most abundant rock types in Earth's continental crust.
Field identification & locations
